Abstract: The present invention provides a rolling roll that has a shaft, which rotates around an axis and has one end that is connected to an output shaft of a rolling mill, and is configured such that a tubular sleeve member is mounted to a portion of the shaft on the side of another end, and a rolling ring, which is formed from a hard material, is fixed to an outer circumference of the sleeve member, wherein an inner circumferential support part is disposed on an outer circumferential side of the sleeve member; the rolling ring is supported by the sleeve member via the inner circumferential support part; a pressing member and a pressing mechanism are disposed on the other end side of the rolling ring; and the pressing member and the pressing mechanism press the rolling ring toward the one end side, thereby fixing it.

Abstract: The present invention is to provide a rolling mil roll including a rolling mill ring and a metal base in which a tensile stress applied to the rolling mill ring located along the outer circumferential face side is reduced; and then cracks thereon are prevented from occurring. The rolling mill roll 10 includes: the rolling mill roll 11 made of cemented carbide having rolling sections 13 on its outer circumferential face 11a; and the metal base 12 located on the inner circumferential face of the rolling mill roll 11. The circumferential interface 14, where the rolling mill ring 11 and the metal base 12 face each other, is fixed radially around its axis L by a contact pressure derived from a fitting section, and also is bound with an adhesive agent M.

Abstract: Annular rings are securely fixed to a shaft in a manner rendering them difficult to come loose, and easily mounted and removed. The rings, in the form of sleeves 21 and 22, are fitted over the outer periphery of a shaft 2 and fastened by a plurality of spacers in which a spacer 25 on one end of the rings is pressed by a belleville spring 27 which is compressed and deformed, and a spacer 23 on the other end of the rings is pressed by a head part 29b of a bolt 29 which is substantially parallel to an axis 0. The bolt 29 with a head is screwed to a screw hole 28a of a tightening nut 28 screwed to a screw part 2b of shaft 2.
